8 Claims.

This invention relates to improvements in machines for lmaking impregnated twisted cords, and one of the objects of the invention is to provide a machine having a reservoir containing a suitable impregnating material with means for continuously drawing a plurality of fibrous strands in converging relation through the ma'- terial in the reservoir thoroughly to impregnate the several strands and simultaneously to twist the strands within the material thereby to embed the impregnating material within the entwined strands.

Another object of the invention is to provide means for coating the impregnated and entwined strands to insure a uniform product. l

More particularly the invention relates to machines for making pyrotechnic fuses, suchas are known as a quick match fuse or a black match fuse which comprises a plurality of strands oi fibrous material impregnated with a suitable combustible' match-impregnating composition such as gun powder. Fuses such as` are known as quick match fuse or black match fuse have heretofore been made by hand or by the use of crude slowly operated machines, such as machines in which a plurality of strands are drawn by a hand operated reel through the matchimpregnating composition and associated in parallelism without twisting.

One of the principal objects ofv the present invention is to provide a machine for making a quick match or black match of very considerlable length in which a pluralityof fibrous strands are drawn in converging relation through the combustible match-impregnating l composition and simultaneously twisted within said material to embed the material within the entwined strands, and which can be operated at a very greatly increased speed over usual machines and methods of making such articles.-

A further object of the invention is to provide a machine for making quick matches orblack matches and in which the impregnated yor entwined strands are coated with a similar composition lto insure uniformity in the burningof the fuses when severed to predetermined lengths.

`A further object of the invention is toprovide a machine of the character described with novel the impregnated and` a machine of the character described in which the restarting of the machine will cause the traversing mechanism to move in thereversev direction, with similar means for stopping the machine at the end of said traverse.

A further object of the invention is to provide automatic means operable by the traversing mechanismfor stopping the machine with manu--r ally actuated means operable upon restarting ,the machine to reverse the'- direction of movement of the traversing mechanism. f

' Another feature ofthe invention is to provide traversing means with areservoir for the coating material and havingmeans by which the reser voir can be readily removed from the traversing mechanism. 1

Another object of the invention is to provide mechanism for actuating the reel, the traversingl mechanisrn, the mechanism for drawing the strands through the reservoir, and the meansfor twisting the strands' in suitably timed relation l to produce auniformly impregnated and cord or match. i y

Another feature of. theinvention consists in providing means for protecting'the traversing coated mechanism from drippings of the impregnating or coating composition.

`Another feature ofthe invention consistsin A preferred embodiment of the invention is shown in the drawings, in which,`

gear mechanism on line E--S Fig. 4, viewed from the right toward the left, illustrating the reversing mechanism, and means for actuating the same.

The machine shown in the drawings comprisesa base or platform I which is supported upon suitable legs 2 and has mounted upon it an upwardly extending post 3 provided near its upper end with an adjustable collar upon which is clamped parallel laterally extending ends 4 of a conical ring 5 supporting a conical reservoir 6 for the impregnating material. The upper end of the reservoir 6 desirably is provided with a more arng upward extension l. The lower end of the conical reservoir is provided with a lining or bushing `8, preferably of rubber or other yieldable material, having a vertical aperture therethrough through which the twisted strands of fibrous material are led and which are. guided therefrom to a suitable reel. The platform has also mounted upon it a vertical standard 9` having a laterally extending arm III which overhangs the vertical axis of the reservoir Ii. A vertical shaft II, which is rotatably mounted in a suitable journal in the end of the overhanging arm I0, has secured to it a pulley I2 which desirably rests upon a boss at the end of the arm I0. The lower end of the shaft II has secured to it a collar I3 which supports a carrier I4 upon `which .are mounted a plurality of spindles I5 each of which carries a cop or tube I6 of cotton thread, string, or other suitable fibrous material. The carrier I5 is fixedly secured to the shaft II and is spaced from the under side of the arm Ill by a suitable spacing sleeve.

Suitable means hereinafter to be described are provided for rotating the carrier I4 thereby to The strands I'I of fibrous material are led downwardly through the impregna-ting material I8 in converging relation and are drawn axially downwardly through the vertical aperture in the bushing 8 around a guide pulley I9.

The axle of the guide pulley I9 is mounted upon suitable standards and desirably is surrounded by a cylindrical wall 2l) which forms a receptacle to receive any of the impregnatinsr material which may leak through the aperture in the bushing 8. However, the bushing is such as effectively to prevent the escape of any substantial amount of the impregnating material.

As the strands are thus led convergingly downwardly through a very considerable depth of impregnating material each strand is thoroughly impregnated with said material. By reason of the rotation of the carrier I4 upon which the tubes o-r cops of fibrous material are mounted, impregnation of the strands I7 is facilitated and the strands are twisted during their progress through the impregnating material into the form of a cord and the impregnating material is also embedded within the entwined strands, thereby forming a cord in which the fibrous material of the strands are thoroughly impregnated with said material and additional material bound within the entwined strands of the cord.

The bushing 8 in the lower end of the reservoir acts as a die to produce uniform twisting of the strands and to insure uniform cross sectional area o-f the cord which is thus entwined and lled with impregnating material.

'Ihe impregnated cord or match 2| is led upwardly from the pulley I9 over a vertical pulley 22, thence downwardly beneath a vertical pulley 23, and thence around a horizontal pulley 24 to a traveling pulley 25 which is mounted upon a traversing mechanism carrying a guide for directing the same to a positively driven reel upon which the cord or match is wound in non-contacting spirals. The reel may be made of sufficient size and capacity to hold a great length of cord or match and is detachably mounted in a suitable frame in such manner that the reel can be readily removed and transported to a suitable drying chamber or again mounted on suitable apparatus to permit drying of the impregnating material.

A convenient form of reel which is illustrated herein comprises a framework having a central shaft 26 and a series of sets of radial arms 21, preferably four in number, and extending at right angles to each other and connected together at their ends by bars 28 which extend in parallelism to the axis of the reel.

In order detachably to support the reel shaft in such manner that it may be readily removed and transported to the drying mechanism, one end of the reel shaft 2B is provided with an angular socket 29 adapted to fit upon a complementary extension of a reel driving shaft 30 which is mounted in suitable vertical standards 3I and 32. The opposite end of the reel shaft 26 is likewise provided with a socket 3S adapted to receive the end of a stub axle 34 which is rotatably mounted in a suitable bearing in a vertical standard 35. The stub axle has secured to it a collar 36 and a spring 31 interposed between the collar 36 and the standard 35 serves to maintain the end of the stub axle normally in engagement with the socket in the reel shaft 2G. The opposite end of the stub axle is provided with a handle member 38 by means of which the stub axle can be drawn lengthwise against the force of the spring 31 to detach it from the reel shaft 26 and alsoY to permit the reel shaft to be disengaged from its driving shaft so that the reel can be readily removed and replaced.

Suitable traversing means are provided for guiding the impregnated cord or match 2| in non-contacting spirals along the reel until the reel is lled or a predetermined length of cord or match wound upon it.

In the preferred construction illustrated herein the guiding mechanism for the coi'd is carried upon a suitable carriage 39 which is mounted upon parallel track members 40 which extend in parallelism with the reel and is caused to traverse the length of the reel, or other such distance as may be desired, by a screw and a cooperating nut upon the carriage, reversing mechanism being provided to enable the screw to propel the carriage in opposite directions.

Means are also provided for automatically stopping the machine when the carriage has traveled a predetermined distance such as approximately tothe end of the reel in either direction and manually operable mechanism is provided for starting the machine and simultaneously reversing the direction of travel of the carriage. By reason of this mechanism the reel can ber removed from the machine after the guide-supporting carriage has traveled in one direction, a new reel substituted, and the carriage caused to travel in the opposite direction to lill the substituted empty reel without the necessity of returning the carriage to its original starting point, thereby enabling a considerable saving of time which otherwise would be required in filling successive reels.

L be employed.

As illustrated herein the carriage 39 has secured to it at one end a downwardly extending bracket All, see Fig. l, upon which are mounted upper and lower wheels 42 and 83, which engage respectively the upper and lower surfaces of the horizontal flange oi the angle iron track member 4t. A bracket it, which is secured to the produced to insure uniformity in the burning ci the match or the match sections into which the match may be divided for use as fuses.

In the construction illustrated herein the coat-v ing and guiding mechanismfor the cord or match is in the form of a reservoir 6 which may be of rectangular form and which is mounted upon a base lll which rests upon and is detacha'bly secured to the carriage 3S. The reservoir 46, which is supplied with coating composition of suitable 'character preferably a somewhat thinner composition than the impregnating composition, is provided with a guide and seal 4% through which the cord or match 2l is led and atfits opposite 1 end with a somewhat longer guide'and seal i9 from which the cord or match 2| is led to the reel. The base lll of the reservoir and guide has pivotally securedto one'oi its ends a depending bracket 5S upon the lower end of which is mounted aA guide wheel lwhich engages the under face of the track member lll beneaththe carriage-supporting wheel 45.

By reason of this construction the carriage is supported upon the track by the Wheels 42 and l l5 and any tilting of the carriage or thebase of the guiding member is prevented by the guide wheels 43 andi! which underlie the track members 4l). This construction also enables the reservoirto be conveniently removed for the purpose of substituting a different guide member or reservoir.V

' vIt will be understood that while in the preferred construction coating means is employed, other types of guides for reeling the cord may The preferred mechanism `for traversing the carriage illustrated herein comprises a nut 52 which is secured to the under face of the carriage which draws the cord or match through the reservoir for `rotating the carrier upon which the thread tubes or cops are supported to twist the strands of :fibrous material, and for actuating a suitable mixer from which the impregnating material is delivered to the main reservoir 6 in properly timed relation to accomplish the purpose of the invention. The main driving shaft 54h-which isrotated from any suitable source of power (not shown)` is journaled in a suitable bracket 55 in the base of the standard 32, and is direction.

provided adjacent its end with a wormgwhich engages a worm wheel 5l upon a shaft 58 which -is journaled in suitable bearings on said standard. A spur gear 59, which is xedly secured to the shaft 5B, engages a complementary spur gear Si! upon a countershaft 6I which-is mountedinr said standard and which has mounted upon its opposite end a sprocket wheel 62 which drives a sprocket chain 63 which in turn drives a sprocket K 84 which isl iixedly secured to the reel driving i' shaft 3d the angularv end of which detachably engages one endof the reel shaft 2t and rotates j the reel. The reel driving shaft 3B has secured to it a large pulley 65 which drives a belt BS, the leads of which pass over suitable guidepulleys 6'! and 68 and engage and drive thepulley I2 upon the end of the shaft il which supports the carrier for the thread tubes or cops of the fibrous strands which when impregnated and twisted form the cord.

Q The shaft sa, which is driven by the worm 56 and worm wheel 5l, has secured to its opposite end a sprocket t9.' which drives a horizontal sprocket chain T which in turn drives a sprocket wheel H upon a shaft 'l2 which is mounted in journals in the lower frame of themachine vand which has on its end a sprocket wheel '13, Fig. 2-, The sprocket wheel 'i3 drives a vertical sprocket chain M which in turn drives a sprocket pinion 75. upon a shaft 'l5 the ends of whichare-mounted in a suitable stand 'H and in bearingv members mounted upon the base of the standard 9. The

shaft 'F6 has secured to its opposite end abevel gear i8 which meshes with a companion bevel gear 'F9 upon a shaft Si) uponthe opposite end of which `is mounted the drawing pulley 22 for the impregnated cordor match. VThe pulley 22 acts in conjunction with the reel continuously to draw the brous strands through the reservoir v while they are being twisted'into the cord andas above described the cord is guided from the pulley 22 to the guide of the traversing vmechanism by the pulleys 23, 24 and 25'. l

kThe shaft l2, which is mounted in suitable bearings upon the base or platform of the machine, has xedly 'secured to it a gear 8| for driving the screw 58 through suitable reversing Inechanismadapted to cause the guide, orv resergear 8l which is positively driven in one direction "I to the gear 82 upon the screw lin such manner as selectively to rotate the screw in reverse directions comprises a hook-shapedlever 63 the shorter arm of which isv pivotally mounted upon a reduced cylindrical end portion fifi of the screw, i

which is mounted in suitable bearings ,carried by the base, the gear t2 being secured to this reduced portion of the screw shaft. The hookshaped lever B3 has rotatably mounted in it lower and uppermeshing spur gears 35 and 86 so ar" ranged that when the longer armor the lever 83 is in vertical position, as illustrated Fig. 6, neither of the gears S5 and @d will mesh' with the driving gear 8l upon theshaft i2. When, however, the longer arm of the lever 355 is swung to the right `from the position illustrated in 'Fig."6', the gear 86 will mesh with the gear 8i and will thereby transmit rotation to the gear 82 .iny one When, however, the longer armo-f the lever 83 is swung tothe left the gear 85 will be thrown into mesh with the gear 8| thereby transmitting rotation from the gear 8| through the gears 85 and 86 to the gear 82 and rotating it in the reverse direction. By reason of this construction therefore the nut 52 and the carriage 39 for the guide or reservoir will be caused to move alternately in opposite directions lengthwise of the reel.

Suitable means are employed to stop the machine when the carriage with its guide has approached the end of the reel with manually operable means fo-r reversing the direction of movement of the carriage when the machine is restarted. This mechanism as illustrated herein comprises a reversing bar 81 which is slidably mounted in suitable bearing members extending upwardly from the floor or base ofthe machine and is provided with adjustable abutment blocks 88 and 89 positioned to be engaged by the nut 52 which is mounted on thescrew and is secured to the under face of the carriage 39. As the nut approaches the end of traverse in one direction it engages the abutment 88, as illustrated in-Fig. 3, and upon continued movement of the nut moves the reversing bar B1 lengthwise. Similarly when the nut has traversed the screw in the opposite direction it engages the abutment block 88 on the reversing bar 81 and moves the reversing bar in the opposite direction. The movement of either of these abutment blocks by the nut is such as to position the reversing mechanism in neutral position, shown in Fig. 6, and also to actuate mechanism for stopping the machine. The manually operated mechanism for restarting the machine is so arranged as to continue the movement of the reversing bar in the same direction as it was moved by the nut and so to shift the reversing gears 86 and 85 as to rotate the screw in the reverse direction.

The mechanism for accomplishing this purpose comprises a plate 88 which is iixedly secured to and extends horizontally from the end of the reversing bar 81 and has an upwardly offset portion 8| which is slidablymounted in guideways 92 upon a suitable stand 83. The offset portion 9| of the plate 88 is provided with a cam slot the opposite ends 94 and 85 of which are inclined or curved in opposite directions from a central nected to a starting lever ||4 the lower end of neutral position in the cam slot. The cam follower 88 is in the form of a vertical pin the lower end of which engages the cam and the reduced upper end 91 of which is mounted in a slot 98 in a U-shaped cap piece 89 which is .secured to the stand 83. The central portion of the follower pin is reduced and is provided with a horizontal trunnion |88 upon which is mounted a twisted link |8| the opposite end of which is pivotally secured by a bolt |82 to the longer arm 83 of the hook-shaped lever which carries the gears 85 and 86. Obviously when the plate 8| is moved lengthwise in one direction the follower will be carried from a neutral position laterally so as to move the gear 88 of the reversing mechanism into engagement with the driving gear 8| and thereby rotate the screw in one direction. Conversely when the plate 8| is moved in the opposite direction the follower will be moved by the oppositely inclined portion of the slot in the opposite direction and will thus actuate the lever` 88 to remove the gear 86 from engagement with the gear 8| and cause the gear 85 to mesh with the gear 8| so that power will be transmitted from the gear 8| through the gears 85 and 86 to the gear 82 on the screw and rotated in the opposite direction.

In view of the fact that it is necessary to remove a lled reel and substitute an empty one before the reversing operation takes place means actuated by the reversing bar are provided for stopping the machine when the cam follower 86 is in neutral position. This is accomplished in the mechanism illustrated by securing to the plate 90, which constitutes an extension ofy the reversing bar 81, a, supplemental cam plate |83 which desirably may be separated from the plate 98 by a spacer |84 so that the plate |83 is in substantially the same plane as the offset portion 9| of the plate 88. The cam plate |83 is provided with a cam slot having a central neutral portion and end portions |85 and |88 which extend in angular relation thereto, as illustrated in Fig. 4. A cam follower |81 extends downwardly into the cam slot from a block |88 which is slidably mounted upon the plate |83 and has secured to it a rod |89 the opposite olset end of which is pivotally connected by a bolt I8 to the lower arm of a lever (Figs. 1 and 4), and a rod ||2 which is pivotally connected to the lower end of the arm extends to and is suitably connected to a belt shipper, clutch or motor control for stopping the machine. When the cam follower |81 is moved by the cam in the plate |83 to the neutral position designated as N in Fig. 4, the lever lll, which is illustrated in Fig. 1 as in running position will be moved to substantially vertical position, thereby forcing the rod |12 to the right, Fig. 1, and actuating the belt shipper or other mechanism for stopping the machine. The lever may if desired be provided with an upwardly extending handle portion la: which may be actuated as an emergency lever when the machine is running to move the rod |88 lengthwise and force the cam follower |81 from the inclined portion |85 or |86 in the cam slot in the plate |83 to neutral position and thereby stop the machine. Such actuation of the emergency lever l |.r can be made only when the machine is running as it cannot be actuated to move the follower |81 from neutral position into the inclined portion |85 or |86 of the cam slot when the machine is stopped.

The reversing bar 81 is provided with a bifurcated forward end ||3 which ispivotally conwhich is fulcrurned upon a suitable bracket ||5 secured to the floor or base of the machine.

It has heretofore been explained that when the abutment 88 is engaged by the nut and moved endwise to the neutral position illustrated in Fig. 4, the cam plate |83 will be so moved as to place the cam follower |81 in neutral position thereby stopping the machine, and that in order to start the machine the reversing bar is moved further in the same direction, as illustrated by the dotted position to the left of the position in which the abutment is engaged by the nut in Fig. 4. Actuation of the starting lever therefore will move the cam plate |83, shown in Fig. 4.-, so that the cam follower |81 will engage the inclined end |85 of the cam slot, thereby moving the rod |89 and the lower arm of the lever ||8 to running position and simultaneously shifting the driving belt or the motor control to operating position.

When the carriage has traversed lengthwise of the reel in the opposite direction the nut 52 will engage the other abutment 89 on the reversing bar and move it longitudinally in the opposite direction, until the cam follower |81 is in neutral position. To start the machine the starting lever is moved in the opposite` directionl from that previously described, thereby causing the cam follower l'lxto' move along the inclined portion |06 of thecam slot, thus again actuating trolled by the cant slot in the cam plate 9|, will V simultaneously actuate thev gear. shifting mechanism to cause the screw rtombe rotated in theproper direction to propel. the carriage lengthwise of thereel so that the cord vwill bewound spirally upon the reel as abo-ve described'.

.In order to provide .for continuous operation of the machine and to maintain a proper consistency of the impregnating .material means de sirably are provided for continuously or-v intermittently replenishing the impregnating material in the reservoir 6, In the construction illustrated in Fig. l a mixing tank H6 is mounted upon a' suitable support ata considerably higher level than th-e reservoir 6. This'mixing tank is of suflicient capacity to contain `a large amount of the impregnating material which when a fuse. or black match is to be made may be of gun powder or other suitable combustible material mixed or dissolved in 4walter to a suitable fluidity. The mixing tank IG isprovided with a suitable mixer or agitator, such as arms |l8 extending radially from a vertical shaft ||9 which is mounted in a suitable bearing |29 in the supporting frame. The arms I8 may be provided with suitable varies |2| preferably pivotally mounted at the outer ends of said arms.

Any suitable means may be provided for driving the agitator. As illustrated herein the shaft 3G, see Figs. 1 and 2, is provided with'a pulley |22 which drives a belt |23 the leads of which pass over suitably supported guide pulleys |24 andv |25, and engage and drive the pulley y|26 which is fixedly secured to the vertical shaft I9 of the mixer. and |28 le'ad from the mixing tank to the reservoir 6. A suitable valve' |29, which desirablyis provided at the junction ofthe pipes |21 and |28 is provided with an operating handle |30 which may be so manipulated as to provide a suitable passage for delivering theimpregnating composition to the reservoir at a predetermined rate l or which may be intermittently operated tov replenishv the supply of impregnating material in the reservoir. i

A further feature of the invention comprises means for preventing the'dripping of the impregnating material upon the screwl and also minimize the settling of dust upon it. This mechanism as illustrated herein comprises a wide belt |31 of exible materiaLsuCh as canvas, rubber, or leather, which is secured to the under face of` the carriage 39 and extends horizontally above the manner above described.

In the operation of the machine in continuously making impregnated andzcoated fuses (as well `as other forms of` impregnated and coated cords),.tlie impregnati-ng material, such- Communicating pipes or conduits |21.
